Problems solved by technology

[0003] (1) The cloth clips must be clamped and disassembled manually, and usually there are multiple cloth clips on one side of an embroidery frame, and manual disassembly and assembly are required one by one, which is inefficient and labor-intensive for operators;
[0004] (2) The clamping force of the cloth clamp 5 cannot be adjusted, if the clamping force is too large, it is easy to leave indentations on the cloth and even damage the fabric; if the clamping force is too small, the fabric cannot be effectively fixed;

Embodiment 1

[0038] The expandable cloth clamping mechanism of this embodiment, such as Figure 1-2 As shown, it includes a base unit 10, a cloth supporting unit 20, a cloth pressing unit 30 and a driving unit. Wherein, the cloth supporting unit 20 is arranged on the base unit 10, and the base unit is used as the border of the embroidery frame. In practical application, some embroidery frames are only clamped and fixed to the cloth at two opposite sides, and some embroidery frames are clamped and fixed to the cloth at all four frame sides. Wherein, the frame edge for clamping the cloth is composed of the expanding cloth clamping mechanism of this embodiment.

[0039] In this embodiment, the cloth supporting unit 20 includes two oppositely disposed support arms, and a drive cavity 26 is disposed between the oppositely disposed support arms. In this embodiment, the lower end of the support arm is a connecting end and is connected to the base unit, and the upper end of the support arm is a ...

Embodiment 2

[0048] The difference between the expanding cloth clamping mechanism of this embodiment and the first embodiment is that the driving unit is different from the first embodiment.

[0049] In this embodiment, the driving unit adopts a deformable filling balloon tube 50, and the deformable filling balloon tube 50 is connected with a gas or liquid filling system. It should be noted that the gas or liquid filling system is an existing technology, and its specific structure is not the invention point of this application. Conventional technical means will not be described in detail.

[0050] In this embodiment, a preferred structure of the deformable filling balloon tube 50 is as follows: Figure 4 As shown, the deformable filling tube 50 includes an outer limiting tube 52 and an inner filling tube 51, wherein the deformable filling tube 51 is filled with gas or liquid. The effect of the limit tube 52 is to control the maximum deformation of the deformed filling tube, so as to prev...

Embodiment 3

[0052] The expandable cloth clamping mechanism of this embodiment is as Figure 5 , Image 6 As shown, the difference from the second embodiment is that, firstly, one of the support arms is a fixed arm 25, and the other support arm is a movable arm 21; secondly, the configuration of the cloth pressing unit 30 is different.

[0053] In this embodiment, the cross section of the cloth pressing unit 30 is close to a square with one side open, and there is no concave-convex structure between the cloth pressing unit 30 and the cloth supporting unit 20 .

[0054] Of course, as the deformable structural form of this embodiment, firstly, the cloth pressing unit 30 can adopt the same structure as that of Embodiment 1 and Embodiment 2; Concavo-convex structure; thirdly, the drive unit can adopt the eccentric rod shown in the first embodiment.

Abstract

The invention relates to the technical field of embroidery machines, and particularly discloses an expanding type cloth clamping mechanism and an embroidery frame. The expanding type cloth clamping mechanism comprises a basic unit, a cloth supporting unit, a cloth pressing unit and a driving unit. The cloth supporting unit comprises two oppositely-arranged supporting arms, a driving cavity is formed between the supporting arms, and at least one supporting arm is a movable arm; the cloth pressing unit is provided with an accommodating cavity used for accommodating the cloth supporting unit; andthe driving unit is arranged in the driving cavity and used for driving the movable arm to open outwards. According to the expanding type cloth clamping mechanism, no resistance exists between the cloth pressing unit and the cloth supporting unit in the dismounting and mounting process, dismounting and mounting are labor-saving, an automatic connecting part is conveniently arranged between the cloth pressing unit and the cloth supporting unit, and a beneficial structural basis is provided for automatic transformation; and the clamping force can be adjusted according to the movement amplitudeof the movable arm so as to adapt to the cloth with different thicknesses, adjustment is flexible, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of embroidery machines, in particular to an expanding cloth clamping mechanism and an embroidery frame. Background technique [0002] Notification number is that the Chinese invention patent of CN2293578Y discloses a kind of composite material embroidery frame of computer embroidery machine, with reference to the appendix of this patent figure 2 And attached image 3 , wherein the cloth is fixed by the cloth holding post 3 and the cloth clamp 5. This type of cloth fixing method has the following technical defects: [0003] (1) The cloth clips must be clamped and disassembled manually, and usually there are multiple cloth clips on one side of an embroidery frame, and manual disassembly and assembly are required one by one, which is inefficient and labor-intensive for operators; [0004] (2) The clamping force of the cloth clamp 5 cannot be adjusted, if the clamping force is too large, it is easy to leave i...
